http://www.cellular-news.com/story/6156.shtml More manufacturers to support GSM1x Qualcomm says that equipment manufacturers Kyocera, Nortel Networks, Samsung, Sanyo, Spatial Wireless, TCL Mobile and Winphoria Networks are all supporting the development of its GSM1x, a technology that offers a CDMA evolution for GSM operators. Nortel Networks plans to support GSM1x with CDMA2000 1X radio access and GSM core network equipment, and Samsung Electronics manufactures the CDMA2000 1X radio access infrastructure equipment. Spatial Wireless and Winphoria Networks will develop the GSM1x Mobile Switching Node (MSN), which interfaces with both the unmodified GSM core network and the unmodified CDMA2000 1X radio access. Kyocera, Sanyo and TCL Mobile manufacture the CDMA2000 R-UIM enabled handsets, which are software upgradeable to support GSM1x. <snip> GSM1x enables convergence of a GSM/GPRS core service network with CDMA2000 radio access. The GSM1x solution supports SMS and position location, and introduces a GSM1x MSN to interface an existing and unmodified GSM core network with an unmodified CDMA2000 radio access network. GSM1x terminals utilize a standard SIM card and are subject to standard GSM authentication. As a result, operators will be able to offer global roaming and service transparency between CDMA2000 1X and GSM networks without compromising their current infrastructure.
